Hi all- I’m working on a document-based app and making every effort to adopt the behaviors of a modern app. This includes state restoration, described in the current documentation at:
https://developer.apple.com/library/mac/documentation/General/Conceptual/MOSXAppProgrammingGuide/CoreAppDesign/CoreAppDesign.html#//apple_ref/doc/uid/TP40010543-CH3-SW14 Despite my best efforts, I’m not having any success with any actual “restoration”… I’ve never seen any evidence of the system attempting to call the relevant overrides when launching my app, after leaving documents open during a quit or log out. Here’s what I know: - document windows have a restoration identifier. - document windows are set to be restorable. - document windows are confirmed to have a restoration class of my custom NSDocumenController subclass (made solely to catch the calling of restoreWindowWithIdentifier:state:completionHandler:). If I don’t subclass, they are confirmed to have a restoration class of NSDocumentController. - I’ve adopted automatic termination by setting the correct Info.plist entry. What works: I can see encodeRestorableStateWithCoder: being called on my window and on view subclasses that I want to restore state for. What does not work: I never see a corresponding restoreStateWithCoder: get called on the window or views, nor do any of the NSWindowRestoration overrides get called… no restoreWindowWithIdentifier:state:completionHandler: on custom NSDocumentController no restoreDocumentWindowWithIdentifier:state:completionHandler: on custom NSDocument I’ve Googled extensively; there’s so little on the topic that I’m wondering if developers are actively adopting this feature. Does anyone have an app that works properly with state restoration, or have a few snippets or ideas to share? Any help is much appreciated - thanks!
